Top Sgnl Alternatives for 2026
Sgnl focuses on access management. many teams evaluate alternatives for broader agent coverage, different deployment models, or pricing that fits their scale. Here are the top competitors to consider.
Category: Agent Identity & Access
What is Sgnl?
Modern PAM solution that provides just-in-time access management for AI agents and humans.
GuardionAI
Agent runtime governance — EDR for AI agents. Guardion governs every agent command, tool call, and data access inline: a security gateway, runtime guardrails, DLP, and detection & incident response for AI agents.
Why it's better than Sgnl
sub-130ms guardrails latency • 96.3 F1 on the Prompt Security Leaderboard with 0.02% false positives • 50M+ agent actions protected per month
Permit.io
Policy-as-code platform that now includes specialized authorization for AI agents and tool calls.
Okta (AI Agent Identity)
Okta secures AI agents as first-class identities: Auth for GenAI (via Auth0) provides Token Vault, async human-in-the-loop authorization, and fine-grained RAG access, while Okta for AI Agents manages agent lifecycle. Its Cross App Access (XAA) protocol extends OAuth/OIDC so identity providers govern agent-to-app connections, with 25+ adopters including Anthropic, Atlassian, and Slack.
- Standards-based (extends OAuth/OIDC) rather than proprietary controls
- Large partner ecosystem for Cross App Access
Formal
A protocol-aware reverse proxy that parses 15+ wire protocols — Postgres, MongoDB, Snowflake, SSH, Kubernetes, S3, and MCP — and enforces least-privilege policies inline at query level. In 2026 it positions as AI-native PAM, proxying agent access to data stores with PII masking and tool-call blocking. Backed by Thrive Capital and Y Combinator; AARM Core conformant.
- True query-level, identity-aware enforcement via wire-protocol parsing
- No SDK or code changes; works with any driver or ORM
